S.C. Code § 38-13-300
The director may require insurers licensed to write property or casualty insurance in the State to record and report loss and expense experience and any other data necessary to determine whether rates are excessive, inadequate, or unfairly discriminatory. The director or his designee may designate one or more statistical agents, organizations, or advisory organizations to gather and compile this experience and data. In addition, the director may require each insurer licensed to write property and casualty insurance in this State, as a supplement to its annual statement, to submit a report on a form furnished by the department showing the insurer's direct writings in this State and the United States and any information required by Sections 38-13-310 and 38-13-320.
The director may adopt data disclosure requirements developed by the National Association of Insurance Commissioners. If adopted, the NAIC disclosure requirements must be deemed to be in full compliance with the reporting requirements of Sections 38-13-300 through 38-13-360.
